YouGov called on to confirm who commissioned poll on Sunak defeat

British Polling Council asks to see documents showing who commissioned controversial surveys

The British Polling Council (BPC) is looking into controversial YouGov polling used by Conservative plotters to call for Rishi Sunak to be ousted.

The two polls, which YouGov said were commissioned by a mysterious group called the Conservative Britain Alliance with Tory peer David Frost acting as the intermediary, caused shock waves in Westminster when they were published in the Daily Telegraph last week.
